The Claim
In states of hypermetabolism induced by thyroid hormone excess, high-intensity aerobic exercise exacerbates sympathetic nervous system activation, leading to increased heart rate variability, catecholamine release, and metabolic stress beyond compensatory thresholds.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When your body is already working overtime due to too much thyroid hormone, doing intense cardio can push your stress response even further, making your heart race more and releasing more stress chemicals than your body can handle.
